Description
Die Erfindung betrifft eine Vorrichtung zum Bestimmen des Rußgehalts von Rauchgasen laut Oberbegriff des Patentanspruches.The invention relates to a device for determining the soot content of flue gases according to the preamble of the patent claim.
Vorrichtungen dieser Art sind bekannt (AT-PS 2 67 232). Die Genauigkeit der Messung hängt im wesentlichen davon ab, daß über die Kolbenpumpe stets eine gleichgroße Rauchgasmenge entnommen wird. Hierbei haben verschiedene Faktoren einen Einfluß, beispielsweise die Gastemperatur, die Sauggeschwindigkeit, die Wartezeiten zwischen aufeinanderfolgenden Ansaugvorgängen, orts- und zeitabhängige Unterschiede des atmosphärischen Druckes usw.Devices of this type are known (AT-PS 2 67 232). The accuracy of the measurement depends on the essentially depends on the fact that an equal amount of smoke gas is always withdrawn via the piston pump. Various factors have an influence here, for example the gas temperature, the suction speed, the waiting times between successive suction processes, location and time-dependent differences atmospheric pressure etc.
Es ist Aufgabe der Erfindung, die Meßgenauigkeit einer Vorrichtung der eingangs erwähnten Art zu verbessern.It is the object of the invention to improve the measurement accuracy of a device of the type mentioned at the beginning to enhance.
Diese Aufgabe wird ausgehend von einer Vorrichtung laut Oberbegriff des Patentanspruches durch dessen kennzeichnende Merkmale gelöst.This task is based on a device according to the preamble of the claim by the characteristic features solved.
Bei der erfindungsgemäßen Vorrichtung wird der Hub der die Rauchgasmenge durch das Filter ansaugenden Kolbenpumpe in Abhängigkeit von eventuellen Temperatur- oder Druckänderungen so gesteuert, daß stets eine konstante Menge von Rauchgas durch das Filter hindurchgeführt wird, also bei aufeinanderfolgenden Messungen die Gasmenge stets konstant bleibt. Damit sind mit einer solchen Vorrichtung wssentlich ίο genauere Rauchdichtebestimmungen möglich.In the device according to the invention, the stroke is that which draws in the amount of smoke gas through the filter Piston pump controlled depending on any temperature or pressure changes so that a constant amount of flue gas is always passed through the filter, i.e. with successive Measurements the amount of gas always remains constant. This means that with such a device ίο more precise smoke density determinations possible.
Die Erfindung wird im folgenden anhand einer schematischen Zeichnung an einem Ausführungsbeispiel näher erläutertThe invention is illustrated below with the aid of a schematic drawing of an exemplary embodiment explained in more detail
Die Figur zeigt den Prinzipaufbau einer selbsttätig arbeitenden Vorrichtung zum Bestimmen des Rußgehaltes von Rauchgasen durch Bestimmung der Schwärzung eines Filters. Die dargestellte Vorrichtung besteht aus einem Filter 1, das beispielsweise in einem entsprechenden Filterhalter durch eine geeignete selbsttätige Einrichtung zum Einlegen des Filterpapiers angeordnet ist, einer zugeordneten Vorrichtung 2 zum selbsttätigen Bestimmen der Schwärzung des Filters, die in dem gezeigten Ausführungsbeispiel mit Betastrahlen arbeitet, sowie einer Kolbenpumpe 3, die über ein Dreiwegeventil 4 eine vorbestimmte Rauchgasmenge durch das Filter 1 ansaugt. Der Kolben 5 der Kolbenpumpe 3 ist über einen Motor 6 hin- und herverschiebbar. Zu einer Rußgehaltmessung werden die einzelnen Bestandteile der Vorrichtung über eine schematisch angedeutete programmierbare Steuervorrichtung 7 in bekannter Weise gesteuert. Zusätzlich ist noch eine Vorrichtung 8 zum Messen der Temperatur und des Druckes vorgesehen, die außerdem elektronische Schaltkreise enthält, über die mittels eines Servomotors 9 ein längs der Kolbenbetätigungsstange 10 angeordneter Hubbegrenzungsschalter It in Abhängigkeit von der Temperatur- und Druckmessung verstellbar ist. Bei Temperatur- und Druckänderungen wird über den Servomotor 9 der Schalter 11 längs des Hubweges der Kolbenstange 10 entsprechend verstellt, und über den Schalter 11, der mit einem entsprechenden Anschlag 12 der Kolbenstange zusammenarbeitet, wird auf diese Weise temperatur- und druckabhängig der Saughub der Kolbenpumpe 3 entsprechend verstellt, so daß sich eine für die Messung konstante Rauchgasmengenansaugung ergibt.The figure shows the basic structure of an automatically operating device for determining the soot content of smoke gases by determining the blackening of a filter. The device shown consists from a filter 1, for example in a corresponding filter holder by a suitable automatic device for inserting the filter paper is arranged, an associated device 2 for automatic determination of the blackening of the filter, which in the embodiment shown with beta rays works, as well as a piston pump 3, which via a three-way valve 4, a predetermined amount of smoke gas sucks through the filter 1. The piston 5 of the piston pump 3 is reciprocated by a motor 6 can be pushed out. The individual components of the device are used to measure the soot content schematically indicated programmable control device 7 controlled in a known manner. Additionally is nor a device 8 for measuring the temperature and pressure is provided, which is also electronic Contains circuits, via which a servo motor 9 along the piston operating rod 10 arranged stroke limit switch It depending on is adjustable from the temperature and pressure measurement. With temperature and pressure changes is via the servomotor 9 of the switch 11 along the Stroke of the piston rod 10 adjusted accordingly, and via the switch 11, which with a corresponding Stop 12 of the piston rod cooperates, the temperature and pressure is dependent in this way The suction stroke of the piston pump 3 is adjusted accordingly, so that a constant amount of smoke gas is sucked in for the measurement results.
Das Dreiwegeventil 4 ist ebenfalls über einen Servomotor gesteuert, und zwar so, daß beim Ansaugen das Rauchgas durch den Filter 1 hindurchgesaugt wird, nach einer Messung das Gas jedoch unmittelbar aus der Kolbenpumpe 3 nach außen abgeführt wird.The three-way valve 4 is also controlled by a servomotor, in such a way that during suction the flue gas is sucked through the filter 1, but after a measurement the gas is drawn directly out of the Piston pump 3 is discharged to the outside.
